[0031] See also Figure 1-Figure 5 The utility model provides an electric constant temperature water bath, including an outer box 200.

[0032] The inner box 100 for heating food samples in a water bath is installed in the middle of the inner cavity of the outer box 200. A heating rod 110 for heating water is installed at the lower end of the inner cavity of the inner box 100. A water inlet 120 is opened on the left side of the inner box 100, and a water outlet pipe 130 is installed on the left side of the inner box 100.

[0033] A floating assembly 140 for opening and closing the water inlet 120 and the water outlet pipe 130 is mounted at the lower end of the inner chamber of the inner box 100. This floating assembly 140 includes a blocking rod 141 for opening and closing the water inlet 120 and the water outlet pipe 130. A connecting block 142 is mounted at one end of the blocking rod 141, and a floating plate 143 is mounted at one end of the connecting block 142 for controlling the vertical movement of the blocking rod 141. As water vapor evaporates, the water level drops, and the floating plate 143 lowers the blocking rod 141, opening the water inlet 120 and facilitating water flow into the inner chamber of the inner box 100. A U-shaped stopper 160 is mounted at the lower end of the inner box 100 to limit the blocking rod 141, ensuring that it can only move vertically.

[0034] The inner box 100 includes a partition 150 for supporting the container. The container is placed on the upper end of the partition 150. A plurality of sliders 151 are fixedly installed on the outer wall of the partition 150. A support block 170 for supporting the partition 150 is fixedly installed at the lower end of the inner cavity of the inner box 100. The support block 170 is an annular block. The support block 170 divides the inner cavity of the inner box 100 into an upper cavity and a lower cavity. Water is in the lower cavity, and a container containing food is placed in the upper cavity.

[0035] A stopper 171 is fixedly mounted on the upper end of the support block 170. The inner wall of the stopper 171 is machined with multiple chute grooves 172 for limiting the position of the slider 151. When the partition 150 is installed, the slider 151 is snapped into the groove cavity of the chute 172. The chute 172 limits the position of the slider 151, preventing the partition 150 from rotating when scraping water from the lower end of the partition 150. The outer wall of the support block 170 is machined with multiple drainage grooves 173 for guiding water flow downward. Water scraped from the upper top wall of the outer box 200 and the upper inner wall of the inner box 100 flows through the drainage grooves 173 into the lower cavity of the inner box 100.

[0036] The outer box 200 includes a battery 210 to facilitate heating the water by the heating rod 110. A base 220 is fixedly mounted in the middle of the outer box 200 to support the inner box 100. A water tank 1 230 is mounted on the upper left side of the inner cavity of the outer box 200 to facilitate the delivery of water to the inner box 100. A water pipe 231, connected to the water inlet 120, is mounted on the lower end of the water tank 1 230. When the water level drops, the blocking rod 141 descends to release the blockage on the water inlet 120, and the water in the inner cavity of the water tank 1 230 flows through the water pipe 231 into the inner cavity of the inner box 100.

[0037] Water tank 240 is installed at the lower left end of the inner cavity of outer box 200. When the condensed water droplets inside inner box 100 are scraped off and the water level inside inner box 100 increases, float plate 143 drives blocking rod 141 upward, thereby releasing the blockage of water outlet pipe 130. Water in the inner cavity of inner box 100, guided by water outlet pipe 130, flows into water tank 240, maintaining a constant water level in the inner cavity of inner box 100 and ensuring the water bath heating effect. When there is a large amount of water in water tank 240, it can be poured into water tank 1 230 through the water inlet at the upper end of water tank 1 230 for internal circulation.

[0038] A sealing cap 250 is mounted on the upper end of the outer box 200 to seal the upper opening and prevent excessive moisture loss. A motor 260 is mounted on the upper end of the outer box 200 to control the rotation of the wiper assembly 300. A speed reducer 261 is mounted on the lower end of the motor 260 to reduce the speed of the wiper assembly 300.

[0039] A wiper assembly 300 is mounted in the middle of the inner box 100, for wiping the upper inner wall of the inner box 100 and the lower wall of the partition 150. The wiper assembly 300 includes a first scraper 310 for wiping the top inner wall of the outer box 200 and the upper inner wall of the inner box 100. As water vapor evaporates from the inner box 100, it tends to adhere to the upper inner wall of the inner box 100, the inner top of the outer box 200, and the lower wall of the partition 150, forming water droplets. A curved water deflector 311 is mounted on one side of the first scraper 310 to guide water. The first scraper 310 is an L-shaped rod. The curved water deflector 311 includes an inclined plate, an arc plate, and a vertical plate. The end of the curved water deflector 311 near the limit lever 330 is inclined, and the end near the limit lever 330 is higher, facilitating the downward flow of water through the curved water deflector 311.

[0040] The wiper assembly 300 includes a second scraper 320 for wiping the lower wall of the partition 150. A connecting seat 321 is fixedly mounted on one end of the second scraper 320, and a plurality of positioning blocks 322 are fixedly mounted on the inner wall of the connecting seat 321. The first scraper 310 and the second scraper 320 are arranged to recover evaporated water vapor.

[0041] The wiper assembly 300 includes a limiting rotating rod 330 for limiting the first scraper 310 and the second scraper 320. The limiting rotating rod 330 is installed at the output end of the reducer 261 so that the reducer 261 drives the limiting rotating rod 330 to rotate, and the first scraper 310 is fixedly installed at the upper end of the limiting rotating rod 330.

[0042] A connecting rod 331 is fixedly mounted to the lower end of the limiting rotating rod 330. The lower end of the connecting rod 331 is machined with a plurality of positioning slots 332 for limiting the positioning block 322, allowing the connecting rod 331 to drive the second scraper 320 to rotate. The bottom of the connecting rod 331 is machined with threaded holes 333. A bottom plate 340 is mounted on the lower end of the connecting rod 331 for limiting the connection seat 321. Bolts 341 are mounted on the bottom of the bottom plate 340 for engaging with the threaded holes 333 to lock the bottom plate 340.

[0043] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
